Still only a concept as far as I know 
Talking to someone at the dealer this afternoon when I returned the
'Blue Pig' & picked ours up.
It was in London a couple of weeks ago to judge dealer reaction, and it was very good apparantley.
Now the next decision is whether to go 2wd (simpler & cheaper) or 4wd (using the Haldex system like the Octavia 4x4 estate)
